6346.0. "mcc_aes_equal ?" by KETJE::PACCO (Horum omnium fortissimi sunt Belgae) Wed Jul 19 1995 11:01

	How is the behaviour of 'mcc_aes_equal' when using wildcards ?
	When 2 identical AES specifications are used, with partial wildcarding,
	equality is not detected.
	An extract from the code, and a printout of the result follows.
	Normal or not ? Same in TeMIP ?

	Kind regards,
	Dominique.

6346.1Seems OK with TeMIP Framework V3.0TAEC::FLAUWMarc Flauw, TeMIP Technical Office, VBOWed Jul 19 1995 15:2158
    Dominique,

    I cannot reproduce your problem on TeMIP Framework V3.0. The simple
    test I have made gives me a result of TRUE. I used the C++ toolkit as it
    was quicker, but the end result should be identical.

    The entity spec might not exactly be the same however.

    I suggest to QAR it against MCC.

    Best regards,

    Marc.

Hello,

	According to the SRM on mcc_aes_equal:

	  Note that equality testing is not used to implement wildcarding.

	I also found this comment in the DECmcc source code.

	*_AES_EQUAL does not support partial wildcard for the SIMPLE NAME
        * datatype.  to support partial wildcard for lines and circuits,
        * bypass in_e validation for (all) wildcarded instances
        * (it's too costly to check each level in the entity specifier
        * for the type of wildcard and the data type of the wildcarded
        * instance

Regards,
		-Erik.
